Hello! I need some advice/help with matrix math. I’d like to use a 4x4 (opengl) matrix to store my model’s position and rotation so I can just concatenate it with the modelview matrix, but I really don’t understand matrices. Is there a good tutorial which explains how to construct such a matrix and how to extract the position/rotation from an existing one? Thanks in advance…

Your question doesn’t have anything to do with advanced OpenGL coding, but this link might be of help.

Yes, sorry. Now that you say this should have been posted in the beginner’s forum. But thanks for the link.
